The 300-meter-long river runs through an ancient village called Puyuan(浦源村), which is famous for a unique(独一无二的) tradition(传统) of protecting(保护) carp. Although carp are famed as food(食物) in China, locals in Puyan village treat(对待) them like old friends(朋友). Villagers say they would rather starve(挨饿) than kill the fish. People in the village will even hold funeral ceremonies(葬礼) for dead carp. A carp grave(坟墓) site is located in village, said to be the only one in the world.

Through the years, the brook has become a heaven(天堂) for the freshwater fish. Today, there are now thousands of colorful carp in the water.

The tradition dates back to the Song Dynasty (960-1279) when villagers' ancestors(祖先) put carp into the creek as an easy and visible way to test water quality(水质). At the same time, a rule(规则) was adopted to protect the fish.

The 800-year-old tradition has been followed from generation to generation(代), which is now enshrined as intangible cultural heritage(非物质文化遗产) in Fujian Province.
